THE leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited only for high-grade ores.
Under reducing conditions, antimony concentrations may be limited by the solubility of Sb(III) sulfides, such as stibnite (Sb 2 S 3 ). Although cobalt can exist in the +2 and +3 oxidation states, Co(II) is the stable valence state in water
Antimony enters the environment during the mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations of antimony Although part of the slag is frequently reused in the furnaces to reduce volatilization losses (Anderson, 2012 Anderson, C.G. 2012.
The decomposition of arsenic and antimony sulphide minerals at pH 12 was considerably greater than at pH 10; orpiment was the most readily decomposed followed by stibnite, realgar, and arsenopyrite, in that order. The amount of arsenopyrite decomposed in six hours, even at pH 12, was small.
The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation. In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to ...

The process also has application as an antimony recovery process for antimony mines. The process has been extensively tested, including a $4.5m 34 day pilot plant operation on Tampakan concentrate, successfully reducing the arsenic content from 1.1% to 0.1%.
The mineral is usually stibnite and the theoretical maximum antimony content is 71.1%. Recoveries from sulfide mills are generally 80-95%. · "Oxide concentrates" are produced using gravimetric concentrators such as jigs, tables, and spirals.

Antimony is a chemical element.It has the chemical symbol Sb.The symbol Sb is from the Latin name of 'stibium' for the element. It has the atomic number 51. Its atomic mass is 121.8. It is a blue-gray element that is somewhat toxic.
Antimony: Antimony (Sb), a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms (physically distinct conditions that result from different arrangements of the same atoms in molecules or crystals). Antimony is a lustrous, silvery,
volatilizing antimony metal in an oxidizing furnace. It is used ... operations are used in the mineral processing of antimony. These ... C.G. Anderson / Chemie der Erde 72 (2012) S4, 3–8 5 Table 3 Plant capacities of historic leading producers of reﬁned antimony.
Antimony (Sb(V)) in Sb mine drainage has adverse effects on the receiving water environments. This study for the first time demonstrated the feasibility of using sulfate-reducing bacteria (SRB) to convert sulfate ions in SMD into sulfides that reduce Sb(V) to Sb(III) and to form complex with Sb(III) as precipitate.
